Antibody levels to hantavirus in inhabitants of western Santa Catarina State, Brazil

Hantavirus cardiopulmonary syndrome (HCPS) is an infectious disease caused by hantaviruses of the family Bunyaviridae, and is transmitted by aerosols of excreta of infected rodents. The aim of the present study was to determine antibody levels to hantavirus in the population that lives at frontier of Brazil and Argentina. Participated of the study 405 individuals living in the municipalities of Bandeirante, Santa Helena, Princesa and Tunapolis, state of Santa Catarina, Brazil. IgG antibodies to hantavirus were analyzed in sera by an ELISA that uses a recombinant N protein of Araraquara hantavirus as antigen. The results were also confirmed by immunofluorescent test. Eight individuals showed antibodies to hantavirus (1.97% positivity), with serum titers ranging from 100 to 800. Six seropositives were males, older than 30 years and farmers. Our results reinforce previous data on hantavirus circulation and human infections in the southern border of Brazil with Argentina.

Circulação extracorpórea e complicações no período pós-operatório imediato de cirurgias cardíacas

OBJETIVO: Comparar a frequência de complicações apresentadas pelos pacientes, durante o pós-operatório imediato (POI), de cirurgias cardíacas de acordo com o tempo de circulação extra-corpórea (CEC). MÉTODOS: Estudo de natureza quantitativa, descritivo e correlacional com 83 pacientes adultos divididos em dois grupos de acordo com o tempo de CEC. RESULTADOS: Do total de pacientes, 44 (53%) tiveram o tempo de duração da CEC de até 85 minutos e 39 (47 %) tiveram o tempo acima de 85 minutos. As complicações foram comuns para ambos os grupos, sendo as mais frequentes dor e oligúria. No entanto, hemotórax, pneumotórax e infarto agudo do miocárdio ocorreram apenas no grupo com maior tempo de CEC. CONCLUSÃO: A maioria das complicações ocorridas no POI apresentou frequencia semelhante para os pacientes, independente do tempo de CEC.

Biophysical interactions in the Cabo Frio upwelling system, southeastern Brazil

The rising of cold water from deeper levels characterizes coastal upwelling systems. This flow makes nutrients available in the euphotic layer, which enhances phytoplankton production and growth. On the Brazilian coast, upwelling is most intense in the Cabo Frio region (RJ). The basic knowledge of this system was reviewed in accordance with concepts of biophysical interactions. The high frequency and amplitude of the prevailing winds are the main factor promoting the rise of South Atlantic Central Water, but meanders and eddies in the Brazil Current as well as local topography and coast line are also important. Upwelling events are common during spring/summer seasons. Primary biomass is exported by virtue of the water circulation and is also controlled by rapid zooplankton predation. Small pelagic fish regulate plankton growth and in their turn are preyed on by predatory fish. Sardine furnishes an important regional fish stock. Shoreline irregularities define the embayment formation of the Marine Extractive Reserve of Arraial do Cabo making it an area with evident different intensities of upwelled water that harbors high species diversity. Consequently, on a small spatial scale there are environments with tropical and subtropical features, a point to be explored as a particularity of this ecosystem.

Web Scale Discovery Systems – How to assess the best solution

The University of São Paulo has been experiencing the increase in contents in electronic and digital formats, distributed by different suppliers and hosted remotely or in clouds, and is faced with the also increasing difficulties related to facilitating access to this digital collection by its users besides coexisting with the traditional world of physical collections. A possible solution was identified in the new generation of systems called Web Scale Discovery, which allow better management, data integration and agility of search. Aiming to identify if and how such a system would meet the USP demand and expectation and, in case it does, to identify what the analysis criteria of such a tool would be, an analytical study with an essentially documental base was structured, as from a revision of the literature and from data available in official websites and of libraries using this kind of resources. The conceptual base of the study was defined after the identification of software assessment methods already available, generating a standard with 40 analysis criteria, from details on the unique access interface to information contents, web 2.0 characteristics, intuitive interface, facet navigation, among others. The details of the studies conducted into four of the major systems currently available in this software category are presented, providing subsidies for the decision-making of other libraries interested in such systems.

Science publication workshops as a strategy to improve the visibility of scholarly production: the experience of the University of Sao Paulo (USP) - Brazil

The objective of this work is to present the experience of workshops that have been developed at the University of Sao Paulo by the Integrated Library System in partnership with Research Commission. The poster presents the main results of workshops that were made in 2011, in two knowledge areas: life science and engineering, about science publication processes, and directed to graduates, pos-doctorates, researchers, professors and library staff. The realization of workshops made possible identifies gaps in different aspects of scholarly communication such as research planning, search information strategy, information organization, submission process, identification of journals with high impact, and so on, areas where professors and librarians can help. Besides, workshops reveal that the majority of participants believe in its importance. Despite the ubiquity of digital technology that transversely impacts all academic activities, it is imperative to promote efforts to find a convergence between information and media literacy in higher education and university research activities. This is particularly important when we talk about how science is produced, communicated and preserved for future use. In this scenario, libraries and librarians assume a new, more active and committed role.

Les ornements dans l'architecture: comment préserver la mémoire du travail des artisans et des artists

This paper deals with one aspecto f a survey which has been carried out for my doctorate thesis, and with parto f what I have studied within the thematic Project FAPESP concerning the presence of foreign professional in São Paulo, coordinated by Prof. Dr. Ana Lúcia Duarte Lanna, between 2007 and 2011. My purpose is, starting from those thoughts , top ut in evidence the potential of sources and reports relating to the work porocesses of craftsmen and artists decorators linked with the environment of architectural practeces and the decoration of interiors in the first half of the XXth century. That preoccupation has accompanied me since the beginnings of my doctorate work, devoted to the study of the production, the circulation and the modes of appropriation of ornaments in teh field of architecture.
